Questions & Answers about Los días en México son bonitos.
Why is it Los días and not Las días?
Even though día ends in the letter a, it is a masculine noun. Since it is masculine and plural, it uses the masculine plural word for the, which is los. Words like el día are very common exceptions to the rule that nouns ending in a are feminine.
Why is the adjective bonitos instead of bonitas?
Because día is a masculine noun, any adjectives describing it must also be masculine. Since we are talking about multiple days, the adjective takes the masculine plural form bonitos. It might look strange to see días bonitos with mismatched last letters side by side, but the grammar is perfectly matched!
Why do we use son here instead of están?
Is en always used to say in a country?
Yes, en is the standard word used for in, on, or at in Spanish. When you are talking about locations like a city or a country, such as en México, it translates directly to in.
